            <title>[SERVER-70321] Collmod coordinator must not resume migrations on retriable errors </title>
                <link>https://jira.mongodb.org/browse/SERVER-70321</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Collmod coordinator &lt;a href=&quot;https://github.com/mongodb/mongo/blob/0406b63884d9993f0eafd7d6dcd680e0ecdc1a1f/src/mongo/db/s/collmod_coordinator.cpp#L368-L369&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;may resumes migrations&lt;/a&gt; after hitting a &lt;a href=&quot;https://github.com/mongodb/mongo/blob/0406b63884d9993f0eafd7d6dcd680e0ecdc1a1f/src/mongo/db/s/sharding_ddl_coordinator.cpp#L369-L376&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;retriable error&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;This could lead to wrong execution scenario like the following:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Collmod starts, &lt;a href=&quot;https://github.com/mongodb/mongo/blob/0406b63884d9993f0eafd7d6dcd680e0ecdc1a1f/src/mongo/db/s/collmod_coordinator.cpp#L201-L202&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;stop migrations&lt;/a&gt; and enter the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/0406b63884d9993f0eafd7d6dcd680e0ecdc1a1f/src/mongo/db/s/collmod_coordinator.cpp#L247&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;kUpdateConfig&lt;/a&gt; phase&lt;/li&gt;
	&lt;li&gt;Hit a retriable error and &lt;a href=&quot;https://github.com/mongodb/mongo/blob/0406b63884d9993f0eafd7d6dcd680e0ecdc1a1f/src/mongo/db/s/collmod_coordinator.cpp#L368-L369&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;unblocks migrations&lt;/a&gt;&lt;/li&gt;
	&lt;li&gt;Attempt to re-execute the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/0406b63884d9993f0eafd7d6dcd680e0ecdc1a1f/src/mongo/db/s/collmod_coordinator.cpp#L247&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;kUpdateConfig&lt;/a&gt; but this time with the migrations unblocked&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Keep in mind that we can&apos;t simply resume migrations on non-retriable error, in fact even after hitting a non-retriable error we can&apos;t guarantee that the coordinator won&apos;t be recovered and re-executed from a new primary node in case of stepdown.&lt;/p&gt;</description>
